Abstract: Molten lithium electrochemical cells are disclosed. A solid electrolyte separates a molten lithium metal or molten lithium metal alloy from a cathode. The molten lithium cells provide high Coulombic efficiency and energy efficiency at operating temperatures less than 600° C. The cells are useful for stationary energy storage in power grids.

Abstract: Molten lithium-sulfur and lithium-selenium electrochemical cells are disclosed. A solid electrolyte separates a molten lithium metal or molten lithium metal alloy 106 from a molten sulfur or molten selenium. The molten lithium-sulfur and lithium-selenium cells have low over potential, no side reaction, and no dendrite growth. These cells have high Coulombic efficiency and energy efficiency and thus provide new chemistries to construct high-energy, high-power, long-lifetime, low-cost and safe energy storage systems.

Abstract: Devices and methods for purifying lithium from lithium salts, including those with low concentration of lithium salts, are provided. A molten composition comprising a lithium salt is electrolyzed with an anode in contact with the molten composition and a cathode separated from the molten composition by a solid electrolyte capable of conducting lithium ions.
